It's a fun and interesting fact about compression that sometimes  
(depending on the patterns in the data), the compression of a big  
pile of files can be much better than compression of a big pile of  
those same files compressed.

I just did a quick experiment on the tahoe darcs repository and  
learned that while the .tar.gz of the normal repository (which  
contains compressed patches) is about 14 megs, and the .tar.rz of the  
normal repository is about 10 megs, the .tar.rz of the uncompressed  
repository (i.e. a normal repository except that the patches are  
uncompressed -- this is an option that darcs supports) is a mere 7.2
